speciacatien of Letters Patent No. 12,525, dated ivrafeh 1s, 1855.

. To all whom may concern Be it known that LEDWARD VAUGHN, of` Alliance, in theounty ofStark and State of Ohio, have inventeda new and useful Machine for Extracting `Stulnps of Trees out of `the earth and I; do hereby declare that the parts. u t .y y f The arch beams d) are joinedtogether` following is a full, clear, and exact descriptionof the construction and operation of the 1 same, reference being had 4to the annexed l0 drawing, making a part of this specication.

"The following rule to be observed (i. e.)

correspondingtellers, refer to corresponding at the top or overthecenter of the frame,

f `andat the lower ends, are 'secured to the horizontal beams (a) `forming a double arch.

The horizontall beams (a) are supportedby u i brace posts (b `b) and secured by incline braces (G2 0?). The brace posts (b b) resting on sills (c) in V form, the above mentioned frame is irmlysecured by rods andbolts.

y (D)lis a nutthroughwhich the screw (E) passes, said nutpassingthrough` a square mortice` in the sweep and rests in a square recess (mz) in hub (B).

f y (B) is a cylindrical hub secured to plate (n) or' sweep (C) by bolts, 'andhas an inverted groove (c) '1n its lower end, which,

. rests on friction balls (Zi).V

. (g) isa half spherical washer, with a groove in its `top orflatside.,in which Ifriction balls play.

(A) is a concave plate secured to t-he arch beams (cl d) at their center .or top, `by bolts, see `Figures 1` and 4c. i

(e) `is a concave in plate A, Fig. 4, in

i `whichthe half spherical washer plays,

- a stump (see Fig.`

permitting frictions balls (l Z) to `play 1n grooves (i) and (k).`

(E) is ascrew passing through openings (fh and j) in Figs.` 1, 3, 4, `and 5, into nut (D) thereby forminga combination for destroying friction, and permitting screw (E)` and .nut (D) to ositate, and conform to the line of pressure.. y (Gr) is a leverlpassing overthesquare (o) i on the screw (E) to prevent the chain (F) from twistingwhile in the `act of extracting (p p) 'are levers.` r) blocks` orfulcrums. (g g) hingesfor elevatingthe frame `of machine and attaching the trucks (H H) i to sills (C), thedog (o) is thrownback by a cord at top of'lever I) permitting the axle to pass down the path (t) land rest on thelplates (s si). The spherical spring (a).

i in the recess (m) in sill (C), throws the dog (fu) over the axle and the machine is loaded (see Figs. 1, 2, and 6).

The trucks (H H) are secured to the sills (C) by theposts (t) passing through a holeA in the. center of the axle (u), see Figs. 1 and 6. w A

Posts (t) are secured to sills (C), by the plates (si) and crochet braces (see Figs. 1, 2, and 6).

(K) Fig. 7 is a bar screwed to hounds (J J) by bolts passing thro-ugh slots (a) in hounds (J J), said bolts (t) having lugs `(o) at one end and rings ((Z) at the other end, and' are fastenedby turning said rings at right angle and thrown over pins (c).

`The forward trucks are kept in their relative position while moving, by the bar (K), see Figs. 2, 7, and 8. y The hounds of the hind trucks are thrown back on sills (C) and secured by a clasp (see Figs. 1, 2, and 6).

N. B. To set the machine for use, the trucks (H H) are detached from the sills (E) bythrowing the dogy (o) back with the lever (I) the frame is dropped to the ground, and rests on sills (see Figs. 1, 2, and 6).

What I claim as my invention, and desire nto secure by Letters Patent of the United States, is.

1. The arch beams (d (l), the brace posts (Z Z) in combination with. the incline braces (o2 o2), and horizontal beams (0,), making a new and useful, firm and compact frame as set forth in the body of the specifications.

2. Also the combination of a half spherical and groove (i) forming a new half spherical washer (g).

3. Also the combination vof the groove opening (j) with a square recess (m) for the purpose as set forth.

4. Also for the purpose of attaching and. detaching the trucks (H H) to and from sills (E) by the combination of levers (h h), fulcrums (r r), joints (g g), posts (t t), dogs (o) and levers (I) as set forth in specifications.

5. Also the securing of the bar (K) to the hounds (J J) as set forth in specifications.

N. B. Ido not claim any one separate thing i in the above mentioned invention, but do claim the combination is set forth in specilications. I
